Goalkeeper handball DOGSO (inside penalty area)?

I'm not sure there is a better advantage signal than signalling for the goal . . . .

Though in youth games I have had parents--and even coaches--screaming about fouls that happened a second or two before a goal was scored by their team. . . .

I think even better is signalling the advantage a few seconds before the goal and then signalling the goal after it. It shows your good work was by design and not by good fortune.

Seen it in the past though where referees give big advantage signals when the goals go in, really just for show.

I do that if there was a massive call for the free kick / pen which I didn't give because I was waiting to see if they scored.

Then I claim the assist.
